Using split command on a 600MB myImage.iso file.

this command will generate three files, namely imageaa, imageab, imageac, of 200MB each. afterwards we can use the cat command to combine the three to get back the original file, the command goes as follows ...

- prompt# cat imagea* > image.iso

Extracting RPM

Sometimes we are required to extract files inside an RPM file without installing it. For example is when we take binaries from one distribution and use it on another distribution, where RPM is not the default package manager. The rpm2cpio command comes in handy. Check out the given example below ... $ rpm2cpio coreutils-6.9-2.fc7.i586.rpm | cpio -idv ./bin/basename ./bin/cat ./bin/chgrp .... ... [.. etc ] Now you can use the extracted files
